Very often, you’d encounter unleveled terrain as you build. Such times calls for the utilization of constructive and constructional ingenuity to proffer a formidable solution.

This process is referred to as reducing levels in the building industry. There are three possible approaches to achieving this; the most cost-effective one is typically adopted.


Cut: This approach offers the benefit of leaving the soil undisturbed across the site; nevertheless, the expense of clearing the spoil from the site is a drawback.

A ‘cut’ section (Application of cut on site).


Fill: This approach is not advised since it would require deep foundations or acceptance of the possibility of settlement down the road if the building were to be placed on the filled area. Fill should never be added in excess of 600 mm in depth.
